Fermented bed pig manure urine no less litter how is it?

As we all know, the amount of excretion of animals in the breeding process is very large, which causes the ground to excrete urine on the ground inside the house and it is slippery and muddy. In addition, the excrement cannot be decomposed, making the house smell bad and the mosquitoes, flies, and bacteria are breeding. This causes the livestock to be unhappy and the body to be sub-healthy and grow slowly. The use of the fermentation bed in the housing is dry, the air is odorless, and the environment is comfortable. The animals rarely get sick and the benefits are high. So where are the excrement of excrement from the livestock in the pens?

Taking pigs as an example, the nitrogen content in pig manure is relatively high, which is the main factor causing environmental eutrophication and malodorous-NH3 production, and it is the main factor causing environmental pollution. There are three ways to excrete pig manure from the fermentation bed: First, the gas produced by the function of the functional bacteria - including carbon dioxide, carbon monoxide and ammonia, etc., these gases are discharged with the air; Second, in the role of fermentation bacteria Under the production of bacterial substances, these beneficial bacterial substances can be used together with some litter for pigs to feed the pigs, thus virtually saving the cost of feeding; III. Residues in the litter, these residual substances are some non- Protein substances and organic fertilizers formed with beneficial bacteria have become a good way to turn waste into treasure. The moisture in the excreta is transcribed by the heat generated during the fermentation process into the air and is discharged together with other gases produced by the fermentation. The flow of hot gases increases the temperature in the pig house. Therefore, the house will be more dry and comfortable. At present, most domestic manufacturers are wet-type fermentation beds. Although they have also been popularized and applied, some defects have been exposed during the actual application process. For example, the material is too thick, the operation is complicated, and the service life is short. The dry-sauce fermentation bed culture technology represented by the Jinbao dry-spreading fermentation bed has made up for the above defects, and the operation is simple and convenient, the effect is more obvious, and the user's full recognition has been obtained.

Whether it's a wet-type fermentation bed or a Kimberbean dry-type fermentation bed, users who use pigs in a fermentation bed will find that the fermentation bed needs to add some litter for a year and a half. Why? What is the migration and transformation of the elements in the litter?

carbon element

The carbon in the litter material is mainly present in carbohydrates. The vast majority of these carbohydrates are lignin, cellulose, hemicellulose, and other fiber materials, as well as small amounts of low molecular sugars, including monosaccharides such as glucose and sucrose, and disaccharides. In the fermentation process, low-molecular sugars are preferentially decomposed by fermenting bacteria as nutrients, and macromolecular carbohydrates such as lignin are also slowly decomposed by the bacteria, but the decomposition rate is relatively slow compared to pig manure. relatively stable. As the fermentation process continues, active carbohydrates such as carbohydrates and carbon dioxide, especially low-molecular sugars, are gradually decomposed and consumed. The supply of carbohydrates to the fermentation broth is reduced, and the fermentation capacity is gradually reduced. If you do not add fresh litter, use longer litter, the fermentation function will be aging. Carbon is gradually reduced in litter consumption.

Nitrogen element

In fermented mattress materials, nitrogen is mainly derived from animal excreta. Most of the nitrogen in the excreta is converted into nitrogen compounds including ammonia, ammonium salts, and bacterial proteins, as well as a small amount of nitrate, as well as some complex non-proteinaceous nitrogen-containing organic substances. Ammonia and other gases continue to be discharged. Ammonium salts are unstable in the litter and can be converted to ammonia gas, and may also be converted into bacterial proteins, non-proteinaceous nitrogen-containing organic compounds, and nitrates. The nitrogen in the litter has two outlets. One is the conversion to gas emissions and the other is that the litter is eaten by pigs. Nitrogen is a gradually increasing element in the litter.

As feces and litter can produce large amounts of ammonia, carbon dioxide, carbon monoxide and other gases, the experts of Jinbao suggest that the fermentation bed housing must be equipped with a suitable number of skylights and windows so as to ensure that the air inside the house is fresh and the animal body will be able to More robust.

Phosphorus

There are two kinds of phosphorus in feed, one is raw material in feedstuffs, mostly in the form of phytic acid, a small part in the form of nucleic acids, and the second is artificially added phosphate. Phytic acid in the digestive absorption of pigs is not much, most of them with the feces, unless the artificial addition of phytase in the feed, or early fermentation of phosphorus in phytic acid degradation of inorganic phosphate. Phosphorus, which is excreted in urine, exists in the form of phosphates and is one of the more inorganic elements in urine. Phosphorus is the main element of the nucleic acid that composes the bacteria during fermentation. The goldfish fermentation fungus can hydrolyze phytic acid to caproic acid and phosphate. The phosphate portion becomes a nutritional supplement to the pig as the litter is eaten by the pig. Phosphorus, which has not been used up by the bacteria, will remain in the litter with salt as the main form.

metal element

Including sodium, potassium, calcium and other macro elements and trace elements. Metal elements generally do not generate gas, and there are only two ways out of them. One is that bacteria are synthesized as a bacterial substance, and the other is retained in the padding in a salt state, so that the concentration of salts in the litter is gradually increased. If the amount of pig litter ingested is large, the consumption of metal elements and the discharge amount in the excreta remain approximately balanced, and the concentration of salt in the litter is significantly increased slowly, and no salting phenomenon is generally formed. Otherwise, the fermenting bed will run for a long time, due to the salting effect, the activity of the fermenting bacteria will gradually decrease, and eventually the fermentation will fail.

In short, as the fermentation process continues, the content of carbohydrates such as sugars and cellulose in the fermented mattress materials gradually decreases, and the excreta residue such as nitrogen substances and metal salts gradually increase. From the appearance point of view, due to the gradual decomposition and consumption of structural materials such as cellulose and lignin in the litter, the elasticity and toughness of the litter continue to decline, tending to become pulverized and becoming more and more easy to compact, and the color of litter has also increased. The more dark brown it is, the more it changes to nearly black, eventually becoming organic fertilizer.

Understand these principles, then we can boldly use dry fermentation bed for high-quality, high-yield pig raising chicken, which will make our breeding work easier and more efficient. For details, please contact: Beijing Huaxia Kangyuan Technology Co., Ltd. Telephone Toll Free Hotline
